But there’s a problem. While it’s a simple matter to build mirrors and beam splitters for photons, it’s extremely difficult to do that for matter waves. As a result, matter-wave interferometers are ...

(PhysOrg.com) -- When a spinning laser gyroscope is placed near a super-cooled rotating ring, the gyroscope accelerates a bit in the same direction as the ring, and scientists aren’t sure why. The ...

Gyroscope designs used in inertial navigation systems (INS) fall into three basic groups: the classic spinning-rotor mechanical gyro (still in use in specialized situations due to its superior ...

Molecular machines, much smaller than single cells, may one day be able to deliver drugs to kill cancer cells or patrol your body for signs of disease. But many applications of these machines require ...

The modern smartphone is only possible because of sensors. Their svelte form factor conceals accelerometers, magnetometers, temperature sensors, a GPS unit, and gyroscopes. They all consume volume and ...

The first gyroscope was invented in 1852 by Leon Foucault (a traditional mechanical gyroscope of this general type is shown in Fig 1). Foucault thought that he could measure the rotation of the earth ...

To make a solid crystal, molecules are generally so tightly packed together there's no room for any movement. It means that solid crystals -- despite their strength and durability -- have generally ...
